Application: kwin_wayland (6.3.0) ApplicationNotResponding [ANR]: false Qt Version: 6.8.2 Frameworks Version: 6.11.0 Operating System: Linux 6.13.2-arch1-1 x86_64 Windowing System: Wayland Distribution: "Arch Linux" DrKonqi: 6.3.0 [CoredumpBackend] -- Information about the crash: So basically, whenever i press alt+tab to switch windows, my screen goes full black, I see a line of random characters (@ if I remember correctly) and then plasma restarts. I just stumbled into this issue which seemed to occur every time I press alt+tab, i'll have a look if it still repeats after rebooting and after pushing this error. If that's relevant, I had wallpaper engine installed, which is now removed as it was causing issues (and caused a full system block yesterday). I am now using picture of the day. For extra context, I have two 4k screens, one 60hz the other 144hz on an nvidia gpu with open source drivers. The crash can be reproduced every time. -- Backtrace (Reduced): #5 QBackingStore::size (this=0x0) at /usr/src/debug/qt6-base/qtbase/src/corelib/tools/qscopedpointer.h:90 #6 0x000070de04c8f211 in QSGSoftwareRenderLoop::renderWindow (this=this@entry=0x5558b659a4b0, window=<optimized out>, window@entry=0x5558b61dc4f0, isNewExpose=isNewExpose@entry=true) at /usr/src/debug/qt6-declarative/qtdeclarative/src/quick/scenegraph/adaptations/software/qsgsoftwarerenderloop.cpp:86 #7 0x000070de04c8f9d1 in QSGSoftwareRenderLoop::exposureChanged (this=0x5558b659a4b0, window=<optimized out>) at /usr/src/debug/qt6-declarative/qtdeclarative/src/quick/scenegraph/adaptations/software/qsgsoftwarerenderloop.cpp:196 #8 0x000070de031ef840 in QWindow::event (this=0x5558b61dc4f0, ev=0x7fff9fe0ec70) at /usr/src/debug/qt6-base/qtbase/src/gui/kernel/qwindow.cpp:2668 #9 0x000070de03cff0ca in QApplicationPrivate::notify_helper (this=<optimized out>, receiver=0x5558b61dc4f0, e=0x7fff9fe0ec70) at /usr/src/debug/qt6-base/qtbase/src/widgets/kernel/qapplication.cpp:3296 Reported using DrKonqi
Created attachment 178491 [details] New crash information added by DrKonqi DrKonqi auto-attaching complete backtrace.
Updated the system, rebooted, and the issue is still there. From my testing, the working task switchers are: - Cover Switch - Flip switch And by working I mean that they don't crash, but the rendering is still broken. These just cause a crash : - Compact - Large Icons - Sidebar - Thumbnail grid
